Two meshes are provided for the brain atlas: a low-resolution mesh and a high-resolution mesh.
The low-resolution mesh, (2L), has 70226 nodes, 423375 tetrahedral elements and 119554
triangular surface elements (6916 for scalp surface, 12780 for CSF surface including
ventricles, 61026 for pial (gray-matter) surface and 38832 for white-matter surface).
The high-resolution mesh will be announced soon.

4. Tissue optical properties

The optical properties of the brain atlas was described in
(Fang2010) Table 2 (the same properties were first used in
(Fang2009b)). The properties for scalp/skull and cerebro-spinal
fluid (CSF) are based on (Custo2006) and those for gray and
white matters are based on (Yaroslavsky2002) at 630 nm.
